To all whom it may concern:

Be it known that I, LUnwIe Sonora, a subject of the King of Hungary, residing at Vicnna, in the Province of Lower Austria and Empire of Austria-Hungary, have invented new and useful improvements in Safety Devices for the Mouths of Vessels Containing Volatile Combustible Liquids, of which the following is a specification.

The wire fabric cylinders, by which flames are prevented from flashing into vessels containing volatile combustible liquids, are usu ally protected against being damaged by introduced funnels and the like, by means of an inner lining made of perforate sheet metal. In order to keep the requisite stiffness, this sheet metal lining can only have a limited number of perforations, and in order to efiectually protect the wire fabric the perforations must be of small diameter. In this manner the free passage area for the liquid is too small so that the filling of the vessel becomes a tedious operation. In order to do away with this drawback, the safety device is, according to my invention, made in the shape of a sheet metal cylinder or prism having longitudinal slots, closed at the outside by hollow ribs made of wire fabric.

sheet metal bodies provided with longitudinal slots and hollow wire fabric ribs, by which these slots are closed, consists in shaping them. of a wire fabric, the weft of which is equidistant points replaced by sheet metal strips.

For facilitating the escaping of the air while the vessel is being filledwithout-iinpairing the safety provided by the. d vice is adapted to be secured in an opening in the vessel has a narrow annular passage formed in inane from different points of this passage, narrow bores alternately lend to the inner hollow space or the vessel and to the open air.

In order that my invention may be better understood, I will describe it with reference to the accompanying drawings, in which Figure l is a sectional elevation of the. safety device constructed according to my invention. Fig. 2 is a cross-section on the line 22 in Fig. '1. Fig. 3 is a cross section of the chamber arranged below the bushing and having its sides formed of a wire-gauze,

the weft of which is, at intervals, replaced 1 by sheet-metal strips. Fig. 4 is a bottom view of this chamber or hollow body. Fi 5 is a view similar to'Fig. 1, but showing the hollow body in side elevation and an other arrangement of the annular passage in the bushing. Fig. 6 is a similar view showing another construction of the said annular passage. Fig. 7 is a sectional elevation of the hollow sheet-metal and wiregauze body, at 90 to, the view Fig. l, and showing the construction of the upper and lower ends. Fig. 8 is a perspective diagram of one half of the bushing, showing the positions of the air passages. Fig. 9 shows a piece of wire fabric, the weft of which is, in certain equidistant places, replaced by sheet metal strips. Fig. 10 is a cross section of a material, of which the safety device may be made, and which consists of strips of wire gauze and strips of sheet-metal riveted to gether.

For making the sheet metal cylinder or prism having longitudinal slots closed by hollow wire gauze ribs, 1 use by'preference the wire gauze represented by Fig. 9, in which the weft is, at equidistant points, replaced by sheet metal strips 1. Of this wiregauze, a length comprising four or more sheet metal strips 1 is so rolled up that the two marginal sheet metal strips 1- double together, whereupon they are connected by means of rivets The lower end of each sheet metal strip 1 is divided into three flaps, of which the two outer ones 6 are bent inwards at right angles, in order to have placed below them the polygonal bottmn plate 8, after having previously curved the wiregauze portions 2 into the requisite shape of hollow ribs and flattened their lower ends. Finally a sheet metal cap 10, having an upturned flange 9 and provided with slots for the passage of the flaps '7 is stuck upon the lower end of the hollow body, and the said flaps are folded inward against the bottom of the cap. Thus it'will be seen that the bottom plate 8 is held between the flaps 6 and 7. At the top of the prismatic hollow sheet metal bedy thus formed, the sheet metal strips 1 and the flattened ends of the hollow wire gauze ribs 2 are inserted into a ferrule 4 adapted to be screwed into the bushing 12 of the vessel. The ends of the sheet metal strips 1 having been pressed into the seats provided for them in the upper end face of the ferrule 4, as

llO

tion 17 on the shown in I, tube 5 is inserted into the i eiruie and the upper end of this tube has an out-turned flange which is clamped between a shoulder on the bushing and the end of the :fei-i'uie It is obvious that the connection of the neck of the vessel with the hollow sheet metal body may be performed in any othe: Way, instead of screwing these two parts togeth r.

While the vessel is being iiiied, a narrow groove 13 is (iii in the inside of the hushiiig 152, as clearly visible i *1 and by screwing in. the clampring for the upper wire gauze din-- phrsgm 11, an annular passage is formed. of the said into this annular pass: 1' open sevei'ai narrow bores 15 ps J through the side 01' wa l of The bushing 12 from above and O'iilil iimri'ow bores 16 pass (iO'WPWVRTCiifJ from said snnuhii' passage.
